The upper and lower parts can be connected by screwing together, left turn, then right turn. An O-ring made of flexible PLA in the middle ensures a waterproof seal. The hole at the top allows a string to be pulled through for attachment to a key ring or carabiner, or it can be hung from a necklace. Printing with € coins yields a 1:1 size, but Swiss Francs and other currencies with larger coins require scaling up to 1:1.3 or 1.4. Doubling the size enables protection of larger objects like a car key against water.
